Moyo is a fetal heart rate monitor for use during labor. It uses Doppler ultrasound for intermittent and continuous monitoring, helping healthcare professionals detect abnormalities and enable timely obstetric interventions.

Product contains lithium-ion battery.

This product cannot be shipped to the USA.

Accurate and efficient detection

Moyo uses a 9-crystal Doppler transducer to detect fetal heart rate, which may enable faster detection compared to single-crystal Dopplers. It provides accurate readings within ±2 bpm, supporting timely and informed clinical decisions during labor.

Supports clinical decision-making

Moyo provides an automated method for determining baseline fetal heart rate that may enhance reliability and reduce observer variability compared to manual calculations. This helps clinicians recognize non-reassuring fetal status and intervene appropriately, thereby enabling appropriate obstetric interventions.

Designed for mobility and comfort

The abdominal belt allows mothers to move freely during continuous monitoring. Moyo is preferred by both mothers and birth attendants for being more comfortable and reassuring compared to traditional methods.

Highlighted features

  1. Supports both intermittent and continuous fetal heart rate monitoring.

  2. Supports comparison of fetal heart rate (FHR) with maternal heart rate (MHR).

  3. Ideal for low-resource settings.

  4. Allows maternal mobility during continuous monitoring.

  5. Enables monitoring of several patients at the same time, improving workflow efficiency.

  6. Activates an alert if the baseline shows bradycardic or tachycardic values.
